Abstract
Several cultural factors including planting date, plant density, leaf pubescence, leaf color and reflective wheat straw mulch exhibited an e ffect on the development of Aphis gossypii populations in cotton. The retarding effect of the wheat straw mulch on aphid development appeare d to result from an increase in light intensity on the underside of co tton leaves. Application of the insecticide, cyhalothrin (Karate(R)), to stimulate cotton aphid population growth resulted in a rapid increa se in aphid numbers but also appeared to mask the effects of cultural control factors.
